1, Why does it connect to WiFi on first time, and fail the next time?
When you first time set up, MMDVM hotspot will generete pi-star set up hotspot, which you'll
connect with, and goes into pi-star and then visit 192.168.50.1 for configuration.
If you connected to your home network/home wifi, it will remember your home wifi.
Therefore, when you open pi-star and try to update your configure, there will be no pi-star wifi.
If you came across this situation, here're two methods to log in and update you configure:
A, Visit http://pi-star on your browser, log in pi-star and configure. If you're on macOS, iOS or Windows 10 tablet, please visit http://pi-star.local.
B, Find your Device IP on your home network routers, and log in with that IP, and update your configure.

I have a Yaesu FT-70DR handheld radio. It does conventional analog as well as C4FM/Fusion/FSY digital. This MMDVM has no problem connecting to it. If you aren't into Yaesu, this MMDVM can also do DMR, DSTAR, P25, and other modes. There's even the capability to cross mode on some modes.
Set up was easy. Turn the MMDVM on; wait a couple minutes; look at your tablet, smartphone, pc, or laptop for wifi connections. Besides the WIFI you're expecting to normally see, you'll see a new one called Pistar. Once you know that IP address, you can log into it and set it up to USE YOUR WIFI. I bought this one because it came with a micro-usb to ethernet dongle. I wanted to plug directly into my router and not use wifi. I still set up the wifi to get use to it, but I find ethernet is more stable with all things. If you only want to use wifi, you can buy this same exact MMDVM from the same seller here on amazon for a lower price. NOTE: If you're going to use ethernet, there's two Micro-USB ports on the MMDVM. Looking at them, put your power (Cell phone charger with more than 1.5amp (1500ma) into the RIGHT plug. Most outer Micro-USB. Plug the ethernet dongle into the micro-usb to the LEFT of the power. I had it the other way around (You'd think it wouldn't matter), but then the MMDVM ONLY saw the WIFI. It didn't see the ethernet. When I swapped the plugs, my router saw the ethernet and gave it an IP address and the MMDVM gave priority connection to ethernet over wifi.
This is definitely a great device. If you don't need the ethernet, get the $105 one. Same thing. You can always buy the ethernet dongle later if you really want it. I do recommend that you educate yourself on how an MMDVM works, the Pi-Star operating system, and how to get your radio to connect to it. It's not hard. It's not rocket science. But if you don't prepare a little before jumping in, you'll get frustrated. Simply go to youtube and type in MMDVM setup or MMDVM and your radio model; or something similar. You'll find a ton of videos on it. Don't forget to send Al Gore a thank you note for making the internet possible. But after watching a couple videos, it's very easy to set up. There aren't any on the ethernet connection. It should have been plug and play, but I learned through trial and error about the ports and priority to make it work. But I had the wifi connected, and my radio connected, in less than 15 minute. (With prepping by watching some youtube videos). Then go to the pistar.uk site and find all the reflectors, rooms, repeaters, etc. whatever your radio calls them, and you can go to those places and talk away. I've had this for 4 days and have spoken to other hams in about 15 states and 4 countries already.
Also, mine came with firmware from March 2019. That's not bad, but there is a newer one out. When you go to pistar.uk there is a download section where you can get the most recent firmware. (Watch a youtube video on that also and you'll be fine).
1. 5v cell phone or similar Power supply of 1.5amp. Mine is plugged into a usb port in my network router being I'm using ethernet.
2. Make sure the SD Card is class 10. Mine was, but verify it. It came with a 16gb card, but even an 8gb is more than enough. Just hard to find 8gb.
3. Update the firmware if it's not the newest 4.1.2 . When you log into the MMDVM, look at the very top right of the page and you'll see the firmware version. Mine was 3.x.x something or another.
4. Watch videos on how to set it up.
5. Go to pistar.uk for any details about the software.
6. Go to the the "Jumbospot and other mmdvm hotspot" facebook page, join, and ask questions. People are great at helping.
Hope I provided enough info. If you know what a hotspot is; know what it's for; definitely want to buy one; then this is a solid choice. No need to spend $280+ on an Openspot 3. Plug, that is completely sealed. These MMDVM have an external antenna jack. So I personally didn't use the 1-2 inch uhf antenna it cam with. I put on one of my spare dual band 15" whip antennas for my portable. 3.5db gain over the little thing it comes with. The stock antenna is fine for around the house. With my whip, I can go about a block away down the street. When you're in the house area, keep your radio transmitting at LOW POWER. But if you go further away, then you can go back to higher power. The MMDVM only puts out 10mw. But you don't want to be 10 feet away in your shack and shove 5 watts down it's throat. Anyway; if you're interested in a hotspot for your ham radio, this is an excellent choice.
UPDATE: After roughly a week I finally got this to work. Now that it’s running I am happier and won’t be returning it. However the instructions are extremely lacking on this. They are not helpful at all.
